Rose hips are the fruits that form on some species of rose plants. The rose hips themselves are one of the richest sources of Vitamin C. I first came across rosehip oil in this article where the author said her friend’s acne scars faded after using rosehip oil. She also said she tried the oil on 3 different people and each of their skin problems got resolved with this oil. I saved the article but never got a chance to try the oil.
